To all whom may concern:

Be. it known that I, 'lsmisrwnbrlmo'ion Horse, a citizen of the United-Sates, residing at New'York, in the city ,a d county of New York,hav pinvented certain new and useful Improvements in Metallic Casks orBarrels; and-I ddhereby declare the follow ing to be a full, clear, andexact description of the invention, such as will enable others skilledin the art to which-it appertains to .make'and use the same.

1,-The particular object of the invention is teproyrde a metallic caskor barrel, capable of retaining a considerable gas-pressure, andserviceable as a delivery receptacle for gasc'ohtaining liquids, such asmalt liquors,'or the like, and one which is also preferably providedwith heat insulation, whereby it tends to maintain. the originaltemperature of its contents against changes from CODV8C-' tion andradiation. In the accompanying drawings, I have illustrated in threefigures the preferred embodiment of my-inventiou', using the samereference characters to indlcate the same parts throughout.

F igurejl isacentralvertical section'of my improved cask or barrel;'Fi 2is an end elevation,.and Fig. 3 isa sectional detail of the bung.

My improved barrel is characterized by 'the employment of a doublemetallic shell made up of an inner shell a and an outer shell b,'thisdouble shell affording a light and cheap construction which may be giveninsulating properties either by packing the space between the twocylinders with a noncond'uctor-of heat such as asbestos or mineral wool,'or the like, or by exhausting the air from the space between the twocylinders to create a partial vacuum therein. The

purpose would depend upon the limiting conditions arising from thediflicul'ty of cre- 'ating and maintaining the vacuum, as comparedwiththe valve of the insulation thereby secured, and it will be apparentthat the spacezbetu-centhetwo cylinders, even if filled with air, wouldafford a substantial insulation,

Inithe'particular formillustrated in the draw'ings,.'the barrel shape isproduced b impartmga-slight bulge to the inner an outer shel1's,.tl 1ebulge being just enough so: that the inner shella. may ass through theends of the outer shell 6 w en the parts of the barrel' arebmgassembled. It will be understood, however, that this particular degreeof bulge is not an essential feature of the invention and may bemodified to suit the requirements of any particular case, or

the inner and outer shells may assume a truly cylindrical form.

-The circular heads c and d of thebarrel,

which are preferably made of pressed steel,

are provided around their circumference with continuous right-anglereturn sections 6, preferably made integral with the head and merginginto the circumferential portion thereof through a strengthened annularedge portion f. This strengthened annular edge portion 7 of the head isgrooved as at g to receive the edge of the inner shell when the rightangle return is placed over the outside thereof, as indicated in I thedrawings and in assembling-the barrel the'inner shell is riveted to theinwardly extending flange of the right-angle return portion, as shown.and calking within the groove 9 isrese'rted to to ,make a gas tightjoint. The inner shell carrying'the heads is secured to the outers'hell, and the space between the two shells is closed, by annularchannel hoops m and n, the inner leg of each of which takes over theoutwardly extending flange of the right-angle return e and is anchoredin an" annular groove 0 1n the upper surface ofthe strengthened annularedge portion f of the head, permitting calking at that point. The outerleg of each channel hoop overlaps the outer shell ahdmay conveniently bese cured thereto a'l bng their meeting lines by brazing, welding orotherwise; and for. 'greater security the bottom of the channel 1svpreferably provided with grooves, as shownin Fig. 1, to engage the upperedges of'the outwardly-extending flange of the rightangle return e,f andof the outer shell. In order to prevent an injurious attack upon.

the metal by the contents of the caskioriOO barrel, I line the innershell with a neutral or insoluble rotecting glaze, as indicatedat p, andwhici may be of any suitable material such as shellac or a silica glaze.

For the purpose .of giving access to the 105 interior of the cask orbarrel to permit. repair of the lining-andthe like,.I formin 1; one ofthe heads-c, an opening closed by an interposed elpsure' g which is so cnstr cted.

.in place by a series-of seat of any known ing flange or tenon r, agasket being interposed between the flange or touch and the bottom ofthe groove, The closure 9 is held blind-set countersunk screws t. Thisheadc is also provided with a bung-hole 14 adapted to receive abungconstruction. It will be observed that the closure 9 is so arrangedthat the internal pressure of the gases tends to close .it more'tightly, but it may be removed to permit access to the'interior of thebarrel by removing the screws}? and turning the closure within thebarrelso that the narrower portion of its elliptical section ma pass throughthe wider portion of the elliptical'opening-and thereby be withdrawn.

It is convenientto provide in the cask or barrel so constructed a doubleshell thereof, for purposes which will readily be understood, and tothis end I proceed as follows, it being understood that the belocated'in any convenient The bung-hole is formed by inter-posing threemembers in the shell,

these members being innerand outer thread ed sections 'v and w supportedin alinement with one another and in engagement with the shells by theannular floating nut or union 0:. The threaded sections a and w areturned over at their opposite ends to infold the edges of the innerandouter shells, and the meeting ends of the sections are ground toaccurate contact with each other when driven in on their threads to ameeting pointwithin the annular nut or union w.

The overturned end portions of the sections a) and w preferably havedouble annular shoulders asindicated at a" so that the innor shouldersseat against the floating union and the ed tween the inner shoulders andthe ends of the said union.' In constructing the barrel the, threadedsection 1) is placed within the inner shell and projecting therethrough,the annular nut is then screwed onto the threadedsection' until it seatsagainst the shoulder thereon and the inner shell. Then after the outershell has been put in place the outer section 11; is passed therethroughand tightly screwed into place within the union.

By this construction the sections 1) and 'w are accurately centere bythe union, and, by virtue of the fact that their meeting ends arebrought into contact with one another, they form a continuous bung-holewith a smooth bore and the screw threads are probnng-hole in the gesofthe shells are anchored be- -tected 'from injury, by blows occurringwhen a spigot is inserted. Furthermore, in the preferred constructionillustrated, a double ground joint is provided at each end of the union,onebetween the union and the inner shoulder on the member I; or :w, and

the other between the outer shoulder and the shell; and any necessityfor accurately grinding the opening in the shell is avoided.
